Lindsay Lohan finds Ugly Betty tough

London, (ANI): Lindsay Lohan found her cameo role in Ugly Betty tough, says co-star Vanessa Williams. The Mean Girls actress had made an appearance in four episodes of the comedy series last year (08) as Betty's former childhood enemy Kimmie Keegan.

However, Lohan was reportedly stunned to find how hard the cast members have to work to produce each instalment, compared to the laid-back pace of movie sets. And Williams believes the experience taught the film star a valuable lesson.

"It takes 10 days to do one episode of Ugly Betty and we work gruelling, gruelling hours because we've got a lot of production, which you can tell," the Daily Star quoted Williams as saying.

"You watch for an hour and you see the production on stage, you see how intricate our episodes are. You know, we don't have the luxury that the film world has, or the time. She (Lohan) was on for three, I guess three episodes or so, and she got a taste of what it's like to be on our set," she added.
